Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed a tracking error detecting apparatus for an optical head, which includes a semiconductor laser apparatus, a diffraction grating, a beam splitter, an objective lens and a photo-detector, in which a laser beam from the semiconductor laser apparatus is divided into a main beam and two side beams at both sides of the main beam by the diffraction grating, the three beams are introduced through the beam splitter and the objective lens to an optical record-ing medium, beams reflected on the optical recording medium are introduced through the objective lens to the beam splitter and reflected thereon, the reflected beams are made incident on the photo-detector and detected outputs of at least two beams of the three beams from the photo-detector are used to produce a tracking error signal corresponding to the tracking state of the main beam on the optical recording medium.  In this case, the reflection of the side beam of the reflected beams on the optical recording medium which passes through the objective lens, the beam splitter and the diffraction grating and returns to the semiconductor laser apparatus is suppressed at a laser beam emission end face to thereby reduce the influence by the skew of the optical disc on the tracking error signal.

Abstract: COMPACT, SOUND-ATTENUATING MUFFLER FOR HIGH-PERFORMANCE            INTERNAL COMBUSTION ENGINE             by RAY T. FLUGGER           ABSTRACT A compact, sound-attenuating muffler for a high-performance internal combustion engine is disclosed in which the muffler casing (21) has an elongated transverse cross-section with a height dimension of only slightly larger than the height dimension of the inlet exhaust pipe (22) and a width dimension in the range of about 2 to 4 1/2 times the height dimension,  The muffler includes a divergently tapering planar first partition (36) which causes gases to be expanded only in a horizontal plane toward the side walls (38,39) of the muffler and further includes a second partition (41) formed to contract or converge the gases in a horizontal plane toward a central opening (42).  The first partition (36) has a cup-shaped back surface so that contraction of the gases around the back side of the first partition (36) is highly effective in attenuating sound, and both partitions are sloped in a direction toward the outlet (28) from the muffler so as to minimize the generation of back pressure, which is not substantially greater than the back pressure in a straight pipe.

Abstract: A B S T R A C T     An air release valve for sphygmomanometers in the form of a flow metering device in an air outlet duct comprising a length of a flexible tube as part of said duct and a pressure member which is displaceable against the valve tube by means of a pivot lever, so as to collapse one tube wall against the other to close the cavity of the valve tube and to produce an initially very gradual and later progressively greater open-ing response, when the pressure member is retracted and the valve tube is allowed to return to its open state.  The valve tube may be an arcuate tube portion extending freely between two parallel spouts of the air outlet duct, or it may be a straight tube portion confined in a longitudinal groove of the valve housing. A U-shaped leaf spring between the valve housing and the pivot lever provides a valve closing force, finger pressure against the pivot lever produces a controlled valve opening action.

Abstract: DISTRIBUTION LINE SWITCHGEAR CONTROL               INCLUDING A LOCKOUT TARGET     Abstract of the Invention A  distribution  line  switchgear  control  is disclosed which  is particularly  suitable  for  use with recloser switchgear which requires small amounts of power from the control for  operation.   The  control  is most usefully powered for continued operation by small amounts of line current provided through a power source current transformer and  includes multiple capacitors which are arranged  in a cascaded control  power  supply having  a plurality  of  isolated  stages.    The  line  current  is precisely  monitored   through   sensing  means   current transformers by the control which causes the recloser to trip, reclose and lockout, as is appropriate to protect the  distribution  line  and  distribution  electricity. Inhibit means prevent the control from issuing a trip signal, unless sufficient energy exists in a trip portion of the cascaded power  supply.   A variety of volatile timers  and  counters  enable  the  control  to  cause  the recloser to trip,  reclose and lockout.   Initialization means,  sensing  the  cascaded  power  supply,  and  a non-volatile  state  memory  responsive  to  trip,  close  and lockout signals of the control, cause the initialization of  the  volatile  and  non-volatile  elements  to  prevent inappropriate control signals.

Abstract: ABSTRACT            An electrographic touch sensor having Z-axis capability.  In one embodiment, a uniform resistive coating (30) is applied to one surface of a substrate (12) and within this coating (30) orthogonal electrical fields are produced.  Overlying the resistive coating is a flexible sheet (40) having a conductive layer, and interposed between the resistive coating and the conductive layer is an array of a material (32) having a substantially greater resistivity than that of the resistive coating (30).  A Z-axis coordinate of a touched point on the sensor, related to the pressure force applied, can be obtained.  This Z-axis coordinate is related to the change in the effective contact resistance between the resistive coating and the pick-off sheet caused by the pressure/force, and that change is "enhanced" by the high resistance array and thereby enables different values of pressure/force to be determined.

Abstract: ABSTRACT:         In order to reduce the cost and design efforts in the transmission and storage of signals, it is necessary to operate the analysing and synthesizing filter bank with a maximum sampling rate reduction.  For the special case of a two-channel filter bank a solution is known which is com-monly referred to as quadrature-mirror filtering, in which the occurring spectral aliasing components are compensated for in the synthesizing filter bank.  By interconnecting the above-mentioned two-channel filter banks in accordance with a tree structure, a filter bank having a larger number of channels and a maximum sampling rate reduction can be realized.  For the case in which a maximum sampling rate reduction in the filter bank is not required, the combina-tion of a digital polyphase network and a discrete Fourier transform processor can alternatively be used.  In order to enable a maximum sampling rate reduction also when the above-mentioned combination is used, the M complex sub-band signals resulting from dividing the input signal with the aid of a digital polyphase network can be subjected to a further sampling rate reduction by a staggered sampling rate reduction of the real and the imaginary sub-signals. As a result, the aliasing distortions occurring at the maximum sampling rate reduction can again be compensated for in the synthesizing filter bank.

Title: Coated abrasive product having radiation curable  binder
Inventor: BOETTCHER THOMAS E
IPC: B24D3/28

Granted: 1989-05-09
Abstract: Abstract This   invention   relates   to   coated  abrasive products  having  a  resinous  binder  which  holds  and supports abrasive granules on a backing sheet.        In the manufacture of coated abrasives, the make coat  resinous  binder  and  abrasive  granules  are  first applied  to  the  backing,  then  the  size  coat  resinous binder is applied, and finally, the construction is fully cured.  Generally,   thermally  curable binders  provide coated abrasives having excellent properties, e.g. heat resistance.        With polyester  or  cellulose  backings,  however, curing temperatures are limited to about 130° C. At this temperature,  cure  times  are long.  The long cure times necessitate the use of festoon curing areas.  Disadvan-tages  of  festoon  curing  areas  include  formation  of defects  at  the  suspension  rods,  inconsistent  cure  on account of temperature variations in the large festoon ovens,  sagging of the binder,  and shifting of abrasive granules. Furthermore festoon curing areas require large amounts of space and large amounts of energy.        This invention provides a coated abrasive product comprising  abrasive  granules  adherently  bonded  to  at least one major surface of a backing sheet by a radiation curable resinous binder material. The binder material can be used to form the make coat, size coat, or both coats. Alternatively, the  binder  material  can  be  used  in embodiments where only a single binder coat is employed. The radiation curable resinous binder material comprises a copolymer formed from a mixture comprising (1) at least one  monomer  selected  from  the  group  consisting  of isocyanurate derivatives having at least one terminal or pendant acrylate group and isocyanate derivatives having at least one terminal or pendant acrylate group, and (2) at least one aliphatic or cycloaliphatic monomer having at least one terminal or pendant acrylate group.
